Hide div class if total equal to 0

Hello!

I’m struggling for a few days to solve a problem. I have a plugin for a floating cart from MarketPress, it’s a free plugin, I want to make it hide when it’s empty but it doesn’t work.
I’ve added an if statement where the code is underlined but it doesn’t work. Can you help me please?
Cheers,

here is the code

[CODE]<!– Load JS –>
<script type=”text/javascript”>

jQuery(document).ready(function () {

// floating cart
jQuery(document).ajaxComplete(function(e, xhr, settings) {
var tot = 0;
var cart_tot = 0;

<?php if ( $showcartitem == ‘yes’ ) { ?>
jQuery.each(jQuery(‘#cart-section td.mp_cart_col_quant’),function(){
var qty = jQuery(this).html() – 0;
if(!isNaN(qty)){
tot += qty;

}
});

jQuery(‘.floating-cart span.cart-total-items’).html(tot);
if (tot <= 0){
jQuery(‘.floating-cart’).hide();
}

<?php } ?>

<?php if ( $showcartamount == ‘yes’ ) { ?>

jQuery.each(jQuery(‘#cart-section td.mp_cart_col_total’),function(){
cart_tot = jQuery(this).html();
});

jQuery(‘.floating-cart span.cart-total-amount’).html(cart_tot);

<?php } ?>
